PerturbData: Age perturb proxy data

In EarthSystemDiagnostics/simproxyage: Simulate Age Uncertainty in Climate Proxy Records.

Description

This function age perturbs input proxy data given on a reference chronology by mapping the proxy values onto a perturbed chronology.

Usage

PerturbData(t.pert, t.orig, x)

Arguments

t.pert	numeric vector with the age perturbed chronology to map the proxy data onto.
t.orig	numeric vector with the original reference chronology of the data in x.
x	numeric vector of the proxy data to perturb.

Details

The mapping is performed by index matching after rounding of the perturbed age values to integer values (while perturbed ages from BAM are integer, non-integer ages can result from tranferring to a Brownian Bridge process (see BrownianBridge)).

Value

Numeric vector with the age perturbed proxy data of the same length as x.
